Sun has launched upgrades to its Sun Storage 7000 family of disk arrays that double the performance and capacity from a maximum of 288TB to 576TB in a 4U (7-in) space. The company is also now offering high-speed InfiniBand connectivity to its array and Remote Direct Memory Access (RDMA).

Sun said it had doubled the performance of the Sun Storage 7410 Unified Storage System by upgrading it with up to four six-core AMD Opteron processors, twice the DRAM cache - up to 512GB - and new 2 TB capacity drives.

Including Sun's recent announcement of its F5100 Flash Array, which allows users to add solid-state drives into the 7410 Unified Storage System, the company said recent benchmarks showed performance increases of up to 107% running common MCAE applications such as MSC-Nastran and Ansys.

Sun also announced two InfiniBand switches. The Datacenter InfiniBand Switch 72 provides a dense switch fabric in a 1U (1.75-in) space for Sun server clusters up to 72 quad data rate (QDR) InfiniBand nodes. The switch can be used with the Sun Blade 6048 Modular System and the Sun Blade 6048 QDR NEM to scale up to 576 servers and storage systems.

The Sun Datacenter InfiniBand Switch 36 is a 1U, 36-node QDR InfiniBand switch for midrange enterprise applications.
